Application filed llay 15, 1996. Serial No. 316,934.

To all 'whom t may con cern Be it known that I, Cnr-lanas E. Mo- MANs, a citizen of the United States, residing at N ew York, in the borough of Manhattan and State of New York, have-in-l vented certain newand useful Improve# niente in Bottle-Closures, of which the following is a specilication.

This invent-ion relates to bottle closures.

The objects of the invention are to nnprove the construction of such devices; furthermore, to increase their etliciency in operation, and to decrease the expense attending their manufacture and application to a. bottle.

With the. foregoing' and other objects in view, which will appear as the description proceeds, the invention resides in the conn'- bination and'arrangement of parts., and 1n the details of construction hereinafter described and claimed as apracticaleinbodinient thereof.

ln the acconn'ianying drawing, forming part of this specication:,Figure l is a Side in section of a bottle provided with a cap constructed in accordance with the present invention, one of the caps being shown disposed above the improved bottle. Fig. l'L1 is a side view of the cap which is shown in section in' Fig. l. Fig. 2

showing a slightly modilied onstructirm. Fig'. 2 is a side view of the cap shown in section on the bottle in Fig'. 3 is a vertical section Otanother modified construction. F ig. 4 is a view similar to Fig'. 3, with the parts separated. Fig. 5 is aside elevation, showing the invention in connection with a jar. Fig. 6 is a vertical section of' the construction shown in Fig. 5.

Lilie re'ereluze numerals iinlicate corresponding parts in the different figures ot thc drawing.

The reference numeral l indicates a bottle or jar which may be of any suitable forni,

size, shape and construction. Bottle l is :formed adjacent to the upper end thereof with an annuh r rib or shoulder 2. Extending; upward troni the rib or shoulder f2 is a plurality of separated spiral threads such as 3, 4l. lach of the thrcads'S-i is adapted to be eiigag't-.d by an inward projection upon a cap such as 5 which may be crimped or rougheiied around its peripheryxas indi-I cated at (i in order to facilitate its application to and removal from the bottle. The

inward projectionson the cap 5 preferably are produced by notching or stamping inward a. portion of the lower edge thereof as indicated at 7. Each of the notches 7 pret'- erably is formed end, as indicated clearly in Figsjl, 2 and 6, the incline of the upper end of the notch being the saine as the incline ot' the shoulder or thread 3% which said notch is intended to engage iii-applying the cap to a bottle. The cap 5 is formed in its top with a depression such as 8, and is provided in- 'teriorly with a disk such as 9 of any suitable niaterial, the disk 9 being adapted to be forced closely against the upper end of thebottle by means of the depression 8, in order to close said bottle in an air-tight manner.

The constructionillustrated by Fig. 2 is exactly the same as that illustrated by F ig. l, except that the bottle is provided with two more closely related separated spiral threads and the cap 5 is formed with an additional nuiuherrof notches ll having.,r inclined upper ends to engage said threads. lt willy be apparent therefore that the invention can be carried out by using two or in sonic cases even more separated threads.

It will be observed from F igs. l and 2 that the separated threads extend upward from the annular rib or shoulder 2. For this reason it is only necessary to give the cap a. partial revolution in order tolock it i-n position upon the bottle. Furthermore, it will be observed that when the cap is 'reversely rotated, the notches will ride up the threads so as to release the cap quic'dy Vfrom its engagementwith the bott-le.

The constructions illustrated in Figs. 3 to G inclusive are practically the saine as those shown in Figs. l and r2', except that the bottle or jar is 'abbeted as indicated at 12 to receive aninner seal or disk such as 13., f

rlhe disk 13 may be either fiat as indicated in Figs. 3

and t, or dished, as indicated in Figs. 5 and 6. When a dished disk is enr ployed, the deprcssionB strikes against the dished portion ot the disk so as to Hatten the saine and cause it to expand in diameter, so as to forni an air-tight seal in the upper end of the bottle or It is well known that in using a jar orl bottle having the ordinary forni of single piral thread, it necessary that the cap s be also threaded. Furthermore in apply 'ing the old form of threaded cap it is with aninclined upper y necessary to give the same a plurality of revolutions in order to apply it to the bottle.

- According to the present invention the exoughly etlicient in operation.

Changes in the precise embodiment of invention illustrated and described may be made within the scope of the following claims without departing from the spirit ofA the invention or sacrificing any vantages.

Having thus described the invention what is claimed as new is:

l. A bottle or jar having a rabbeted portion, a Adished disk adapted to lit said rabbeted portion, and a cap adapted to flatten said dished disk to increase its diameter.

2. A bottle or jar having a rabbeted portion, a dished disk adapted to lit into said rabbeted portion, and a cap having a depression in its end adapted to flatten the dished disk to increase its diameter.

3. A bot-tle or jar having a rabbeted portion, an annularrib, and a plurality of separated spiral threads extending upward from the rib, a dished disk fitted into the rabbeted portion, and a 'cap having a depression to Hatten the dished disk and a plurality of inclined notches in the lower of its adredge thereof to form inward projections to engage the separated threads. i

4t. A bottle or jar provided with-an annular shoulder and a plurality of superposed separated threads connecting at their lower ends with said shoulder, in combination with a cap having one or more inpunched projections at its lower edge to engage said threads, said projections being provided with inclined upper walls having an angular arrangement with relation to Athe lower edge of the cap conforming to the angular arrangement of the threads with relation to the shoulder, whereby stops are provided at the junction of the threads with the shoulder to limit the turning movement of the cap, the relative angular arrange ment of the parts being such as to adapt the cap to be screwed down into close Contact with the shoulder so that the inclined upper walls of the projections and basal edges of the inner walls thereofwill respectively bear1 against the threads and shoulder and exe t resisting pressures to prevent injury to tlr projections when the cap is screwed on.

A bottle or jar provided' with an elongated neck having an annular rib or shoulder and a pluralityI of superposed separated threads connecting at their lower ends with said shoulder, in combination with a cap having one or mpre inpunched projections at its lower edge to engage said threads, said projections being provided with inclined upper walls having anangular arrangement with relation to the lower `edge of the ,cap conforming to the angular arrangement of the threads with relation to the shoulder, whereby stops are provided at the junction of the threads with the shoulder to limit the turning movementof the cap, the relative angular movement of the parts being such as to adapt the cap to be screwed down into close contact witha dished disk adapted to fit said rabbetedA portion, and a cap having a depressien to flatten said disk, and means to engage the separated threads.

In testimony whereof I affix my signature in presence of two witnesses.
